Deep Brain Stimulation & the Finite Element Method

In certain neurological conditions, such as Parkinson’s disease, there is overactivity in central areas of the brain that fine-tunes the movements of the body. This can result in symptoms such as tremor and rigidity in the patient. These symptoms can be reduced greatly by destroying or jamming a small part of the overactive area.

I work with technical methods for this such as radio frequency (RF) ablation, where a temperature-controlled high frequency current is used to thermally coagulate tissue, and deep brain stimulation (DBS), where a chronically implanted electrode is used to jam the pathologic activity. I perform simulations with the finite element method (FEM) in order to estimate the affected volume around the electrode and I perform diffuse reflection spectroscopy and laser Doppler flowmetry during implantation of electrodes in order to confirm correct placement and avoid rupturing larger blood vessels. I have also been a postdoc at ICFO – The Institute for Photonic Sciences in Spain where I studied effects on blood volume, oxygen saturation and flow with optical techniques.
